Hello,
I'm currently preparing my PhD in material science and I encounter a problem. it's difficult or near impossible to make a tensile strength test pieces according to ISO 6892 Table D.2 dimensions(specifically the length of the specimen is too great).
I am yet to make a mold for making the material to be studied, and I want to make it as small as possible while being able to produce standardized test pieces, the process will be centrifugal casting, and the end product will be a relatively thine cylinder, making the mold too long will require too much material per test and might make the mold unstable with the available equipment, which will lead to irregularities in the specimen.
But again in E.2.2 is mentioned :"Transverse or longitudinal test piece dimensions other than those given in Annexes B and D can be specified in the product standard."
and I am wondering what is meant by "other". is it the dimensions mentioned in Table B.1 or random dimensions according to what is possible?
